Application filed January 27,1906. Serial No. 298,262.

To all whom it may concern.-

Be it known that I, OLIVER COLBORNE, a citizen of the United States of America, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Pie-Making Machines, of which the following is a specification.

This invention relates to pien1aking machines; and its main object is to save time,

labor, and expense 1n the manufacture of pies by avoiding mechanisms which require the stopping of the pies while performing their respective operations.

Other objects of this invention are to provide a pie-making machine in which the pies are carried along by continuously-moving feeding mechanism and in which the operations of filling the pies, moistening the edges of the crusts, and trimming the crusts are all performed automatically while the pies are eing so carried; to provide an improved and compact arrangement of the supportingframe and conveyer mechanism for devices of this class; to provide an improved form of filling apparatus for'measuring and delivering uniform quantities of filling material to each successive pie, to provide improved trimming mechanism adapted to have a purely rolling contact with the edges of the pie-tins and trim the crusts on the tins while said tins are continuously moving along the conveyer; to provide improved means for automatically discharging the pies from the and to provide an improved form of crust-trimming mechanism which may be readily adjusted to trim,. the crusts of pies of different diameters.

These objects are accomplished by the device shown in the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of a pie-machine constructed according to this invention. tion of the same on the line 2 2 of Fig. 1. Fig. 3 is an end elevation of the crust-trimming mechanism as viewed from the right of Fig. 1. Fig. 4 is a section on the line 4 4 of Fig. 1. Fig. 5 is a detail view showing the relation of the moistening device to the edges of the pie-tins. Fig. 6 is a vertical section of one of the carriers.

In the construction shown the supportingfraine consists of a horizontally-disposed platform or table 5, carried by a central edestal 6. This pedestal is provided with orlzontally-disposed arms-7 and 8, extending tocontact wit Fig. 2 is a horizontal secward each end of the table 5. Verticallydisposed shafts 9 and 10 are journaled in bearings at the outer ends of the arms 7 and 8, respectively. Each of these shafts has rigidly mounted thereon a pair of sprocketsheaves 11, which carry an endless-belt conveyer formed of two parallel link belts 12, rigidly connected with each other at regular intervals by carriers 13, which are adapted for su porting pie-tins at their upper ends, as wil e hereinafter described.

In the device shown in the drawings. the shaft 9 is driven by means of worm-gearing at 14. The shaft 10 is driven from the shaft 9 through the link belts 12.

' Each of the carriers 13 is'provided with a bowl-shaped support 15 at its upper end for supporting a pie-tin at its rim. This. suport is carried by a hollow shaft 16, which is oosely journaled in the carrier 13 and has a friction-roller 17 rigidly secured at its' lower end. A rod through the hollow shaft 16 and is provided with a pad 19 at its upper end adapted to engage the pie-tin and lift it from the support 15 when the rod 18 is raised. Each of the carriers is also provided with a flanged roller 20. These rollers are ada ted to engagethe tracks 21 and support t e conveyerbelt against sagging at points between the shafts.

A sector 22, having a V-sha ed groove-in its periphery arranged to-fit an have friction the rollers 17, is rigidly secured to the sup orting-frame concentrically of the shaft 9. his sector and the rollers 17 cause 18 extends longitudinally.

the pie-tins to be rotated on, their own axes of the sector 22, e arm 7 andis the friction-rollers 17.and to be'again rotated while 'in position for contact with the crust-trimed'in a frame 25, which is mounted u on the table 5 near the shaft 10. A pair of epending swinging frames 26 are hung from a hoi'if zontally-disposed shaft 27, which is jouris rotated through 43 and 44, w

naled in the frames 26 carries a pair of flan ed pulleys 28, and these pulleys support t e belts 29 and 30, which extend along the conveyer at each side of the path of the pie-tins and are adapted to bear in an inclined position u on the edges of the pie-tins, as shown in lgs. 3 and 4. The frames 26 are normally urged toward each other by the spring 31 and i are limited in such movement by an adjustable stop 32, which is adjustably connected to one of the arms 26 and is adapted to engage a lug $3 on the other. This arrangement permi s the trimming-belts 29 and to yie d when in contact with the ie-tins, but normally urges them toward eac other, so as to give the desired ressure for'cutting off the surplus crust. T 1e belt 29 is driven by the pin1on34, which is driven by a bevelgear 35, carried by the shaft 27. The belt 30 is driven by a pinion 36, which meshes with a bevel-gear 37 at the other end of the shaft 27 The bevel-gear is driven by a pinion 38 on a vertical shaft 39, which is connected with the shaft 10 by means of the belt and cone-pulleys. (Indicated at 40.) The belts 29 and 30 are driven at somewhat different speeds to conform with the respective resultant speeds of of the pie-tins which are in contact withsaid belts. It will be seen that, since the pie-tin the contact of the frictionroller 17 and the rack 23, the point of the ed e of the 'ie-tin which is adjacent to the be t 30 will e moving along at a considerably less speed than that of the point which has engagement with the outer belt 29, these speeds being resultants of the rotary motion of the pie-tins and their movement along the conveyer.

In order to adjust the machine for trimming the crusts of pies of different diameter,

the belt 40 is shifted to the cones of the cone-pulleys, the stop 32 is adjusted to suit the new diameter of the pie-tin, and the gear and pinions 36 and 37 are replaced. by others of suitable proportion to drive the belt 30 at the proper speed with respect to the belt 29.

The pie-filling material is carried in a cylindrical receptacle 41, which is removably mounted upon the upper end of the shaft 9 and rotates therewith. The receptacle 41 is provided withfour discharge-spouts 42, which correspond in spacing to the spacing of the carriers of the conveyer. Each of the spouts 42 is plrovided with two sliding valves 'ch are spaced apart sufficiently to measure the proper terial for each pie. hese valves are respectively operated by cams 45 and 46, which are ri dly mounted on the frame, and are arranger? to operate the valves 43 and 44, so that the measuring compartment of each spout between said valves will fill with macorresponding uantity of filling mabearings in the frame 25. Each of thosepoints on the edges so placed-upon the shaft 9 that the pietins will each register with one of the spouts 42 while passing around the shaft 9. While the spouts 42 are discharging their contents into the pie-tins, the pie-tins are at the same time rotated through contact of the friction-roller 17 with the sector 22 This rotation serves to cause the filling material to spread evenly over the tin.

A water-tank 47 is mounted on top of the receptacle 41 and is connected, by means of the two ipes 48, with spraying-nozzles 49, one of which is located at each spout 42 in position to moisten the edgeof the pie-crust while the pie-tin is passim along a'portion of its path around the shaft 9. Each of the nozzles 49 is controlled by means of a springvalve which is normally closed, but which is arranged to open through the engagement of its stem with a track 51, which is connected with the frame and extends around the desired The rotation of the pie-tins while the nozzle is discharging a spray thereon insures an even distribution of moisture around the rim of the crust.

A track 52 is mounted on the frame at the extreme left of the machine and extends along the path of the conveyer, bein inclined upwardly so as to engage the r0 s 18 of the carriers-and wedge said rods upward, raising the pie-tin, as shown in Fig. 1, The pie-tins then pass into the mouth of an inclined delivery-chute 53. As soon as the carrier arrives at the end of the track 52 the rod 18 falls to its normal position, leaving the pie-tin supported by the chute 53. The inclination of this chute permits the pies to be discharged from the machine automatically.

The operation of the device shown is as follows: While the machine is in operation, the conveyer is continuously driven. A pie-tin is placed upon each carrier either automatically or by hand while the carrier is passing along the side of the machine which is at the top of Fig. 2. The lower crusts are then placed upon the tins and the operation of filling the pie takes place while the tin is passing around the portion of the path which is at the right to the shaft 9 in Fig. 2. While the portion of the path of the pietins.

IIO

carrier is passing from the filling mechanism to the crust-trimming mechanism, the upper crust is placed upon the pie. The pie then comes into contact with the belts 29 and 30, which bear upon the ed es of the tin at an angle thereto and out o the surplus fringes of crust. WhIle the tins are in contact with the belts 29 and 30, said tins are rotated through the action of the friction-rollers 17 and the friction-rack 23. The belt 29 travels 6o trimming mechanism.

at the same rate of speed as the part of the periphery which is ad'acent thereto, and similarlythe'belt travels at aspeed corresponding to that of the part of the periphery of the tin which is in contact therewith. The contact between the belts 29 and 30 and the edges of the pie-tins is purely rolling contact,

since the speedsof the adjacent points of the peripheries are exactly equal.

When the carrier reaches the part of its path which is at the extreme left of Fig. 2, the rod 18 rises upon the track 52, and the pie-tin is lifted and deposited upon the chute 53, as has already been described.
